With the rig listed below, will I get any benefit to getting a new AMD 6950 or 6970? Or am I better off saving a while longer and grabbing a full DDR3 capable PC with all the new tech like sandy bridge? Here's my computer specs: AMD Phenom II X4 965 (3.40 GHz, Socket AM2+) ATI Radeon 4870 1GB ASUS M4A79 Deluxe Motherboard 8 GB RAM DDR2 667 (various memory manufacturers) Misc Seagate and Hitachi Hard Drives I'm looking to upgrade my PC for the new crop of PC games this year. While I still think of my PC as high end, it's starting to show a bit more age, especially since I upgraded to 24" screens running at 1920x1200 native resolution. It just can't get a smooth framerate with max detail on my favorite games anymore, on the other hand, I get pretty close, usually requiring a few bumps down in detail, although I prefer not to run lower than native resolution. (For reference, I plan to play Dawn of War 2: Retribution, Battlefield Bad Company 2 Vietnam, Dead Space 2, Dragon Age 2, Deus Ex, etc) I just miss the days of buttery smooth gameplay, and loading up Dead Space 1 PC and feeling the input lag due to performance got to me. However, it's been a little while since I fully built a new system (I've been upgrading over time), and I'm wondering if buying a new video card would make this PC last for another few years. $300 is a lot for a card, but considering I just spent half that getting mounts for my monitor setup, I can afford to be fully happy with my PC performance again.
